Psalm 50:10 For every beast of the forest is mine, and the cattle upon a thousand hills.Do you think that is the literal 1000 hills only?
One thousand as used in biblical books from psalms to the book of Revelation - an especially in the book of the apocalypse which is filled with numers as symbols - one thousand means "man" - or "completely all" -- 1000 = 10 x 10 x 10 -> so as per Judaic numerology, a complete and perfect number.
God owns all the cattle on all the hills in all the valleys which number far more than a thousand.
One thousand cubits is used symbolically four times as the depth of water flowing from below the threshold of the temple (Ezekiel 47:3-6).
In addition you see the symbolic usage of one thousand in Deuteronomy 7:9, Psalm 84:10, 90:4, 91:7, 105:8
This was clearly "very large" not a precise 1000 .
Call no man father seems to be quite unfocused as well.
I'll leave, "This is my body..." for another time.
